Did you know that Vanilla was formerly served as aphrodisiac by Cassanova and Madam Pompadour, and Elizabeth I loved its flavor? This is the first book that provides a complete worldwide coverage of orchids being employed as aphrodisiacs, medicine or charms and food. Opening with an in-depth historical account of orchids (orchis Greek testicle), the author describes how the Theory of Signatures influenced ancient herbalists to regard terrestrial orchid tubers as aphrodisiacs. Doctors and apothecaries promoted it during the Renaissance. Usage of orchids in Traditional Chinese Medicine, Indian Ayurvedic Medicine; by Tibetan yogins and Amchi healers for longevity pills, tonics and aphrodisiacs; by Africans to prepare 'health promoting' chikanda or as survival food when lost in the Australian bush are some highlights of the book. Early settlers in America and the East Indies often relied on native remedies and employment of orchids for such needs is described. Also covered are the search for medicinal compounds by scientists, attempts to prove the orchid's efficacy by experiment and the worry of conservationists.

Nepal is a country of rich biodiversity, with habitats ranging from tropical jungles to the icy peaks of the world's highest mountains. Centred in a global biodiversity hotspot, and hope to a third of all Himalayan species, Nepal's ecosystems are crucial to life across Asia. The Flora of Nepal is the first comprehensive record of this diversity.

A beautiful, richly illustrated book on Europe's wild orchids - perhaps the most enigmatic and popular group in the botanical world. The orchid family (Orchidaceae), numbering some 25,000 species, is one of the world's two largest families of flowering plants. Whilst the vast majority of orchids are found in the wet tropics, Europe accommodates c.130 native orchid species which are equally arranged in dense inflorescences of great beauty. Furthermore, the adaptations encountered in some of the European species are just as fascinating as those of their tropical relatives. This book provides an introduction to the native orchids of Europe. It features four sections: 'Structure and systematics', 'Orchids and the environment', 'Orchid portraits' and 'How to learn more'. This part constitutes the bulk of the book, presenting individual genera in a sequence which reflects their most likely evolutionary relationships. Each genus is introduced by one page of text and illustrated by one or more colour plates on the following pages. The text gives information on how to recognise the genus, where it is distributed, and the estimated number of species it contains - alongside information on the range of environmental requirements and flowering times in the European species. Depending on the genus, additional information may be found on topics such as pollination biology, associated fungi, evolutionary relationships or systematic problems. Beautiful watercolour artwork accompanies the text, making this an indispensable gift for anyone interested in the natural world. Not only is it a useful field guide, it is also a beautiful art book.

Master's Thesis from the year 2015 in the subject Biology - Botany, grade: -, , language: English, abstract: The inhibitory or delaying action of both the synthetic chemicals and naturally occurring phytochemicals against oxidative damage to tissues by free radicals produced in biological system of living organisms is known as antioxidant activity. Since some phytochemicals are responsible for biological as well as medicinal activities, nine wild orchids of Nepal were assessed for total polyphenolics and flavonoids content along with the antioxidant activity. The ethanolic extract of Eria graminifolia pseudobulbs, Gastrochilus acutifolius leaf and root, G. distichus whole plant, Luisia trichorhiza leaf and root, Otochilus albus pseudobulbs, Papillionanthe uniflora whole plant, Pholidota articulata leaf and pseudobulbs, Rhynchostylis retusa leaf, and Trudelia cristata leaf and stem were prepared by Soxhlet extraction. Phytochemicals were detected by previously established protocols with minor modifications. The total flavonoids were estimated with aluminium chloride method and total polyphenolics content with Folin-Ciocalteu phenol reagent method. Antioxidant activity was assessed by DPPH (2, 2-diphenyl-1-picryl hydrazyl) free radical scavenging assay. There was significant variation of total flavonoids, total polyphenolics content and antioxidant activity among the orchid extracts at P = 0.05. The total flavonoids varied with highest in Rhynchostylis retusa leaf (110.68 ± 4.52 mg QE/g) and lowest content in Gastrochilus acutifolius root (22.32 ± 1.10 mg QE/g); total polyphenolics with highest in Trudelia cristata stem (69.68±2.78 mg GAE/g) and lowest content in Gastrochilus acutifolius leaves (11.89±0.64 mg GAE/g). Also, the antioxidant activity varied with highest in Trudelia cristata stem (IC50 79.69 μg/ml) and lowest DPPH radical scavenging activity in Gastrochilus acutifolius leaf (IC50 341.79 μg/ml). However, none of the orchid extracts were as effective as quercetin – the reference compound – in radical scavenging activity (IC50 32.90 μg/ml). Total polyphenolics and flavonoids content and antioxidant activity of selected orchid extracts in this study were higher or lower than medicinal plant and orchid extracts of previous studies with considerable margin. Again, their antioxidant activity was positively associated with total flavonoids and total polyphenolics content. [...]

Slipper orchids are amongst the most popular of all cultivated orchids. They are widely grown and have been hybridised for almost a century and a half. This book covers the tropical American species of three genera of slipper orchids, Selenipedium, Mexipedium and Phragmipedium. Until fairly recently the slipper orchid scene has been dominated by the tropical Asian species of the genus Paphiopedilum, however the discovery of a suite of spectacular new species, particularly in the genus Phragmipedium and of the monotypic Mexipedium xerophyticum,a true missing link, has transformed appreciation of the tropical American slipper orchid species. The new generation of hybrids that have resulted are showy, brightly coloured and long-lasting - favourites on the show bench and in the amateur greenhouse.This is the first monograph in English to cover the tropical American slipper orchids. Written by Phillip Cribb, perhaps the leading orchid taxonomist in the world, together with Christopher Purver, Director of the Eric Young Orchid Foundation, on the Isle of Jersey, renowned for its Phragmipedium breeding program.The authors provide a detailed systematic treatment of the genera and species, including their history,taxonomy, description, keys, distribution, cytology and ecology. A history of the breeding ofPhragmipedium hyrids since the second half of the 19th century deals with the revolution broughtabout by the discovery of the amazing scarlet -flowered P.besseae and the spectacular royal purple P. kovachii. Future breeding trends are also covered and the cultivation of these desirable plants is also discussed.Beautifully illustrated throughout with colour botanical paintings by Carol Woodin, as well as black andwhite line drawings, colour photographs and maps.
